This invention relates to new and useful improvements in a carbonremoving composition.

The primary object of my invention is to provide a compound of thischaracter which is in- 5 troduced into the motor through the spark plugopenings and acts, first, to loosen and eliminate the old carbon on thecylinder walls, valve seats, etc., and second, to coat or glaze thewalls of the cylinders and associated parts 'of the'motor 10 so that newcarbon will not collect for many thousands of miles.

The composition consists of kerosene, creosote, castor oil and amylacetatemixed and blended in substantially the following proportions:

Per cent Kerosene 49 Creosote 25 Castor oil 25 2O Amyl acetate Thecompound is introduced into the motor through the spark plug openingsafter the former has been heated to a temperature at which the water inthe radiator begins to boil and creates a 25 gas which circulatesthrough the cylinders, pround valve openings, under cylinder and pistonrings and associated parts of the motor and penetrates and loosens theold carbon. In doing so,

it gives the motor more compression and the piston rings freer actionand thus reduces gasoline and oil consumption, while producing greaterenergy.

- In practice, the kerosene passes off as a vapor 5 or with the carbonand is used in the mixture as a reagent to aid in the production of gasfrom the other elements of the compound. When the motor cools, this gasis allowed to partly solidify and coats or glazes the cylinder walls,which 10 causes the new carbon to be thrown off as quickly as it isproduced, owing to the smoothness of the cylinder walls.

The several elements of the compound so thoroughly blend with each otherthat the best pos- 15
